The L78M00AB series is a three-terminal positive regulator that provides local card regulation, eliminating the distribution problems associated with single-point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
The L78M00AB/AC series are three‑terminal positive linear regulators offered in TO‑220 and DPAK packages with fixed output voltages ranging from 5 V to 24 V. They provide 0.5 A output current, internal current limiting, thermal shutdown, and safe‑area protection, making them suitable for on‑card regulation in many applications.
The document lists absolute maximum ratings, thermal data, ordering codes, connection diagrams, test circuits, and detailed electrical characteristics such as dropout voltage, quiescent current, short‑circuit current, and thermal resistance. Mechanical dimensions for tape‑and‑reel packaging are also provided.
